Motorola Large Omni-Directional Remote Speaker Microphone (IMPRES) With Nexus Plug (PMMN4113A)

Motorola Large Omni-Directional Remote Speaker Microphone (IMPRES) With Nexus Plug (PMMN4113A)

The PMMN4113A is aimed at users who need ruggedness, flexible audio accessory support, and dependable intelligibility in difficult operating environments. Reseller and specialist radio listings consistently describe it as a large omni-directional remote speaker microphone with a Nexus plug, 3.5 mm audio jack, front and side PTT, volume control, and IP67 sealing.

For buyers searching terms such as Motorola PMMN4113A, IMPRES omni-directional RSM, Motorola Nexus plug shoulder microphone, or IP67 Motorola speaker mic, this model stands out because it combines Motorola’s IMPRES audio ecosystem with a rugged accessory body and multiple connection options. Dealer listings commonly associate it with MOTOTRBO DP4000e, DP3000 legacy, TETRA MTP6000, and some ASTRO APX workflows, though the most consistently repeated compatibility reference is the DP4000e-class professional-radio family.

A remote speaker microphone, often shortened to RSM, lets a user keep a two-way radio on the belt, vest, or harness while speaking and listening through a microphone-speaker unit clipped higher on the body. In Motorola’s product portfolio, the PMMN4113A sits in the premium end of this category, where ruggedness, audio enhancement, and integration with other accessories matter more than low cost. Motorola’s own page presents it as an IMPRES remote speaker microphone with Nexus Audio Jack and Windporting, signaling that it is designed for demanding professional use rather than casual business radio traffic.

The IMPRES branding is especially important here. Motorola says the microphone’s IMPRES technology provides superior audio by suppressing ambient noise, improving voice intelligibility, and amplifying quiet transmissions. That means the PMMN4113A is meant not just to relocate the microphone and speaker, but to actively improve communication quality in the field.

The omni-directional design is another major differentiator. Specialist reseller pages describe the PMMN4113A as an omni-directional microphone, meaning it picks up sound more evenly from multiple directions rather than focusing narrowly like some noise-cancelling microphone designs. In practice, that makes it useful where speech needs to be captured naturally without requiring very precise microphone positioning. This is partly a specification claim from resellers and partly an operational inference based on the term “omni-directional.”

Design and Features

Large-format remote speaker microphone body

The PMMN4113A is consistently marketed as a large remote speaker microphone. That size class matters because large RSMs are typically favored in professional environments where stronger speaker output, easier handling with gloves, and more rugged housings are important. Motorola’s naming and reseller descriptions align on this point.

A large microphone body also gives more room for physical controls and accessory interfaces. Seller listings for the PMMN4113A describe front and side push-to-talk controls, volume control, emergency button, and a programmable button, which makes it more capable than a very simple shoulder mic.

Omni-directional microphone pickup

The defining acoustic characteristic of the PMMN4113A is its omni-directional microphone. Several specialist dealers explicitly call it an omni-directional RSM, which distinguishes it from Motorola’s related PMMN4102B, marketed as the active noise cancelling variant. The omni-directional design suggests the PMMN4113A is meant for broader, more natural voice pickup rather than aggressive directional filtering. This distinction is supported by reseller descriptions and by comparison with the official Motorola page for the PMMN4102 family.

IMPRES audio technology

Although Motorola’s official PMMN4113 page is concise, it uses the same core IMPRES audio language found on the PMMN4102 official page: the accessory suppresses ambient noise, improves voice intelligibility, and amplifies quiet transmissions. Because Motorola’s official PMMN4113 page title identifies it as an IMPRES RSM with Nexus Audio Jack and Windporting, and reseller pages add “Intelligent Audio,” it is reasonable to treat the PMMN4113A as part of Motorola’s higher-performance audio accessory ecosystem.

Nexus and 3.5 mm audio jacks

One of the strongest differentiators of the PMMN4113A is its audio connectivity. Reseller listings describe it as having both a Nexus jack and a 3.5 mm jack. The 3.5 mm output is typically used for a discreet receive-only earpiece, while the Nexus connection supports compatible headsets and hearing-protection accessories.

This combination makes the PMMN4113A more flexible than a closed, speaker-only microphone. It can function as a standard shoulder mic, but it can also become part of a more modular audio setup for covert listening, high-noise work, or headset-based communication. That flexibility is a practical inference from the published jack layout.

Windporting and weather-resistant design

Motorola’s official page includes Windporting in the PMMN4113 product title, and resellers repeat that feature in their spec summaries. Windporting is important because outdoor radio users often lose speech clarity in windy conditions. Motorola and resellers position this accessory as one that remains more usable in outdoor and moving-air environments than simpler microphones.

The accessory is also repeatedly identified as IP67. That rating is one of the clearest ruggedness markers in the public sources, indicating strong dust resistance and water resistance. For field users, that makes a meaningful difference compared with lighter-duty microphones.

Technology and Specifications

Core published identity

Motorola’s official product page refers to the family as PMMN4113, while dealers and resellers consistently list the orderable model as PMMN4113A. The commercial market clearly treats PMMN4113A as the standard purchasable version of this microphone.

Key feature set

Across official and reseller sources, the PMMN4113A is described with the following core attributes:

• IMPRES technology
• Omni-directional microphone
• Nexus audio jack
• 3.5 mm audio jack
• Front and side PTT
• Volume control
• Emergency button
• Programmable button
• Windporting
• IP67 protection.

This is a notably rich accessory feature set, especially compared with basic shoulder microphones that may only offer a single PTT key and no secondary audio integration.

Intrinsic safety and rugged-use notes

Some reseller listings state that the PMMN4113A meets UL-TIA4950 requirements for DP4000e series use and is approved for hazardous environments. That is a significant claim, but it appears in reseller materials rather than on the surfaced official Motorola product page, so it should be treated as compatibility guidance to verify against the radio’s approved accessory list before deployment in hazardous areas.

Radio compatibility

Specialist dealer pages most consistently associate the PMMN4113A with:

• MOTOTRBO DP4000e series
• DP3000 legacy series
• TETRA MTP6000 series
• some ASTRO APX radios.

Because compatibility claims vary slightly by seller, the safest high-confidence statement is that the PMMN4113A is commonly sold for higher-tier Motorola portable radio families, especially DP4000e-class radios.

Applications and Use Cases

Professional business and industrial radio use

The PMMN4113A is best suited to professional users who need a durable shoulder microphone that works well in everyday field conditions. Its large body, IP67 sealing, windporting, and multi-jack configuration make it suitable for transport, facilities, maintenance, industrial operations, and security teams. These verticals are inferred from the accessory’s rugged feature set and the radio families with which it is sold.

Outdoor and mobile operations

Because Motorola highlights Windporting and IP67, the PMMN4113A is a strong candidate for outdoor work where wind, dust, and weather are routine concerns. Road crews, campus teams, events staff, utilities support, and mobile supervisors are all plausible use cases based on the accessory’s published design priorities. This is an inference from the feature set rather than an explicit Motorola vertical list.

Headset-assisted communications

The combination of Nexus and 3.5 mm outputs makes the PMMN4113A useful where users need a shoulder microphone plus an earpiece or headset. For example, a user might want the convenience of an external PTT/speaker mic while still routing receive audio privately through an earpiece. This modular use case follows directly from the published jack configuration.

Hazardous or high-regulation environments

Because reseller sources mention UL-TIA4950 support for certain Motorola radio families, the PMMN4113A may be relevant in hazardous or tightly regulated environments, provided the exact radio-plus-accessory combination is approved. This should always be confirmed from the radio’s official approved accessory documentation before use in such settings.

Advantages / Benefits

Flexible voice pickup

The biggest advantage of the PMMN4113A is its omni-directional microphone behavior combined with IMPRES processing. That can make speech capture feel more natural and forgiving in real use than a microphone that requires very precise positioning. This is supported by reseller descriptions of the microphone as omni-directional and by Motorola’s emphasis on intelligibility and quiet-transmission enhancement in the IMPRES family.

Better accessory integration

The combination of Nexus and 3.5 mm audio connections makes the PMMN4113A more versatile than a standard RSM. It can support a wider range of listening accessories and headset workflows.

Ruggedness for professional use

With IP67 protection and a large-duty form factor, the PMMN4113A is clearly designed for harsher working environments than entry-level business-radio microphones.

Expanded control options

The published presence of front and side PTT, emergency, programmable, and volume controls gives the user more interaction options than a basic speaker microphone. That can improve usability in gloves, high-stress situations, or mixed headset/speaker workflows.
